We divide 79312482 by 645
The aim is to understand the frequency of 645 in 79312482.

Going ahead to step 1:
645 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 645

Let's proceed to step 2:
79 divided by 645 is 0 with a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 79 leaves us with 79.
Bring next digit (3) of the dividend behind the 79 and repeat the process: 793 / 645

Step 3:
645 can be fit into 793 1 times, resulting in a remainder of 148.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 645 from 793, we get 148.
Bring next digit (1) of the dividend behind the 148 and repeat the process: 1481 / 645

Going ahead to step 4:
645 can be fit into 1481 2 times, resulting in a remainder of 191.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 1290 from 1481 and we're left with 191.
Include the next digit (2) from the dividend after 191, then repeat: 1912 / 645

On to step 5:
645 goes into 1912 2 times with a remainder of 622.
The number 2 becomes the next digit in our result. 
Result so far: 122.0
Deduct 1290 from 1912 and we're left with 622.
Include the next digit (4) from the dividend after 622, then repeat: 6224 / 645

Going ahead to step 6:
645 can be fit into 6224 9 times, resulting in a remainder of 419.
Use 9 as the next digit of our solution. 
Result so far: 1229.0
Deduct 5805 from 6224 and we're left with 419.
Grab the next digit (8) from the dividend, add it to 419, then carry on: 4198 / 645

Advancing to step 7:
645 can be fit into 4198 6 times, resulting in a remainder of 328.
Use 6 as the next digit of our solution. 
Result so far: 12296.0
Subtract 3870 from 4198 to get 328.
Include the next digit (2) from the dividend after 328, then repeat: 3282 / 645

On to step 8:
645 can be fit into 3282 5 times, resulting in a remainder of 57.
Use 5 as the next digit of our solution. 
Result so far: 122965.0
If we subtract 3225 from 3282, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 9:
When dividing 570 by 645, we get 0 with a remainder of 570.
Put 0 as the next digit of the answer. 
Result so far: 122965.0
Subtract 0 from 570 to get 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Going ahead to step 10:
645 goes into 5700 8 times with a remainder of 540.
The number 8 becomes the next digit in our result. 
Result so far: 122965.08
Deduct 5160 from 5700 and we're left with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Moving on to step 11:
5400 divided by 645 is 8 with a remainder of 240.
The number 8 becomes the next digit in our result. 
Result so far: 122965.088
Subtracting 5160 from 5400 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

In conclusion, the division gives 122965.088 with a balance of 0.024.
